Abstract
Additive technologies for making products by laser melting of powders have been rapidly developed recently. However, such technologies impose increased requirements on the properties of alloys used for the manufacturing of parts. Laser-melting technologies are a promising direction in the development of metal products due to several advantages, such as: (1) the possibility of manufacturing the complex-shaped parts with internal cavities and thin partitions; (2) significant material savings due to the precise manufacturing of a part of a given shape according to a computer model that does not require the use of subsequent conventional turning, milling, and cutting operations; (3) achieving a higher level of mechanical properties due to increased cooling speeds compared to standard technologies by means of the formation of a more dispersed structure.
Keywords: additive technologies, powder metallurgy, selective laser melting, microstructure, microstructure control, heat treatment.
